FAN ATTACHMENT FOR ROCKING-CHAIRS.

To all whom it may concern:

Be it known that I, ERNEST C. KILLEBREW, a citizen of the United States, residing at Evansville, in the county of Vanderburg, State of Indiana, have invented certain new and useful Improvements in Fan Attachments for Rocking-Chairs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fan attachments for rocking chairs. 1

The object of the invention resides in the provision of a fan attachment for rocking chairs adapted to direct a draft of air upon the occupant of this chair while rocking the same.

A further object of the invention resides in the provision of a fan attachment for rocking chairs, which includes means,

whereby the oscillatory movement of thechair will effect a continuous rotary movement of the fan proper.

A still further object of the invention resides in the provision of an attachment of the character named which will be simple in construction, eflicient in use, and readily applied to any ordinary rocking chair.

With the above and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views, and in which,

showing Mounted at one side of the chair A and rest ing on the floor is the fan attachment indlcated generally by B and positioned in such relation to the chair that the occupant will receive a cooling draft of air.

The fan attachment B comprises a base formed of a pair of superimposed frames 0 and D, the frame C being disposed upon the frame D, and capable of a limited adjust ment with respect to the latter frame. The adjustable connections between the frames C and D is accomplished by forming the frame D with a pair of members 10 and 11 while the frame C is formed with a pair of members, 12 and 13 disposed respectively upon the members 10 and 11 0f the frame D. Each of the members 10 and 11 is provided with a longitudinal slot 14: through which extends a bolt 15. The upper end of this bolt projects through an opening 16 in respective members 12 and 13 and has mounted thereon a nut 17. By this construction it will be apparent that when the nut 17 is loosened on each of the bolts 16 the members l2 and 13 may be adjusted longitudinally of the members 10 and 11 respectively and when so adjusted can be secured against movement by tightening the nuts 17 on the bolts 16.

The members 10 and 11 of the frame D are connected at one end by a member 18, while the members 12 and 13 of the frame C are connected at corresponding ends by a member 19 which overlies the member 18 of the frame D. Rising from the central portion of the member 19 is a standard 20 which supports at its upper end a platform 21. Journaled upon the upper side of this platform 21 transversely thereof is a shaft 22, the ends of which project beyond the adjacent ends of the platform. Fixed on one end of the shaft 22 adjacent the platform 21 is a gear wheel 23, the outer face of which has secured thereto a disk 24 which pivot ally supports on its outer face a plurality of pawls 25.

Fixed on the shaft 22 outwardly of the disk 24 is a pinion 26, the inner end of which reduced to form another pinion 27 adapted for cooperation with the pawls 25. On the end of the shaft 22 opposite to that on which the gear 23 is mounted is fixed a disk 28 which carries on its outer face a crown gear 29. Rotatably mounted in the disk 28 in the axis of the crown gear 29 and projecting outwardly therefrom is a stud 30 which extends through and is fixed to the central portion of an arm 31 one end of which latter terminates in a loop handle 32 and its outer end in a reduced portion 33. Rotatably mounted on the inner end of the reduced portion 33 and meshing with the crown gear 29 is a pinion 34, while a head 35 is rotatably mounted on the outer end of the reduced portion 33 and is operatively connected to the pinion 34 by means of a coil spring 36 encircling the reduced portion 33. The head carries a plurality of fan blades 37 disposed in radial disposition.

Secured upon the upper face of the platform 21 in parallel spaced relation to the shaft 22 is a rod 38. This rod projects beyond the end of the platform 21 adjacent which the gear 23 is disposed. Loosely mounted upon the rod 38 and meshing with the gear 23 is a gear 39 which carries on its outer face a disk 40 corresponding to the disk 24 carried by the gear 23 and having pivotally mounted on its outer end a plurality of pawls 41 disposed oppositely to the pawls 25 mounted upon the disks 24.

' Loosely mounted upon the rod 38 outwardly of the disk 40 is a pinion 42 which has its inner end reduced to form another pinion 43 which cooperates with the pawls 41.

Meshing with the pinion '26 is a rack bar 44 which has its lower end extended in the form of a rod 45 carrying at its free end a journal 46 in which is rotatably mounted a shaft 47. Likewise a rack bar 48 is disposed in mesh with the pinion 42 and has its lower end extended in the form of a rod 49 carrying at its free end a journal bracket 50 in which is rotatably mounted a shaft 51 extending transversely of the rod 49 in the same direction as the shaft 47 extends with. respect to the rod 45. These shafts 47 and 51 carry on their outer end clamps 52 and 53 respectively which are adapted to be detachably secured to respective ends of the rocker of a chair whereby the oscillation of said rocker will reciprocate the rack bars 48. The upper ends of the rack bars 44 and 48 are connected by means of a spring 54 which presses said rack bars into engagement with respective pinions 42 and 26. Extending laterally from the standard 20 is an arm 5-5 and connecting this arm and the rod 49 "is a spring 56. Another spring 57 connects said arm with the rod 45, said springs 56 and 57 also serving to constantly draw the rack bars 44 and 48 into respective engagement with the pinions 26 and 42.

The stability of the standard 20 is enhanced by a plurality of stay bars 58 having their upper ends secured to the standard and their lower ends secured to the base frame C. Connecting the ends of the members 10 and 11 of the frame D opposite to those connected by the member 18 is a gutter 59 in which the rocker A of the chair A is positioned when said rocker is asso ciated with the attachment.

Assuming the parts of the attachment to be in the position shown in Fig. 2 and the clamps 53 and 52 secured to the rear and front end of the rocker A it will be apparent that when the chair A is rocked rearwardly the rack bar 48 will be moved downwardly and such movement of the rack bar will in turn rotate the pinion 42 and this rotation of the pinion 42 will be imparted to the pinion 43 and cause the latter to cooperate with the pawls 41 to rotate the gear 39 toward the rear of the chair A. This rota tion of the gear 39 will in turn rotate the gear 23 with which it meshes and cause the latter to rot-ate the shaft 22. This rotation of the shaft 22 will of course rotate the disk 28 and the crown gear 29 and as the latter meshes with the pinion 34 it will effect the rotation of said pinion. This rotation of the pinion 34 will first tension the spring 36 and when this tension has become sufliciently great the rotation of the head and fan blades 37 will. be instituted. During the movement of the rack bar 48 just referred to, the rack bar 44 is reciprocated upwardly so as to rotate the pinion 26. This rotation of the pinion 26 however, is without effect upon the gear 23 owing to the disposition of the pawls 25 with respect to the pinion 27 hen the chair A is rocked forwardly the rack bar 44 is drawn downward and such movement of said rack bar 44 will effect a rotation of the shaft 22 and in turn the fan head and blades as will be apparent. During the interval in which the reciprocation of the rack bars 44 and 48 is reversed the rotation of the fan head and blades is continuous owing to the stored tension in the spring 36. It will of course be noted that when the rack bar 44 partakes of its active stroke the rack bar 48 is simultaneously partaking of its inactive stroke and vice versa.

In the modified form of invention illust-rated in Fig. 9 the gears 23 and 39 have fixed thereto exteriorly ratchet wheels 60 and 61 respectively. Mounted upon the shaft 22 exteriorly of the ratchet wheel 60 is a lever 62 which carries a spring actuated pawl 63 for cooperation with the teeth of the ratchet wheel 60. Secured to the free end of the lever 62 by means of a ball and socket joint is one end of a rod 63; said rod having mounted on its other end, the clamp 52 in precisely the same manner as said clamp is secured to the rod 45 in the structure previously described. Pivoted upon the rod 38 is a lever 64 which carries a spring actuated pawl 65 for cooperation with the teeth of the ratchet wheel 61. The free end of this lever 64 is connected by a ball and socket joint to one end of a rod 66. The other end of this rod carries the clamp 53 in a manner similar to that in which the clamp 52 is carried by the rod 63. In thisconstruction the oscillation of the levers 62 and 64 will effect the rotation of the shaft 22 and such oscillation is imparted to said levers by the rocking movement of the chair A, as will be apparent.

What is claimed is:

1. In an apparatus of the class described, the combination of a frame including a guide rail for a rocker, a shaft journaled on said frame, a rotatable fan carried by the frame operatively connected with one end of said shaft to efi'ect the rotation of the fan, a pair of rack and pinion elements operatively connected to opposite ends of the rocker, and connections between said rack and pinion elements and said shaft for rotating the latter.
